Abstract

The invention relates to a blind-zone-free GPS device for positioning and navigating land transport vehicles and a receiving method. The GPS device comprises a satellite signal receiving unit circuit, a satellite signal processing unit circuit connected with the satellite signal receiving unit circuit, and a two-dimensional acceleration sensor circuit connected with the satellite signal processing unit circuit, wherein the satellite signal processing unit circuit comprises a baseband processor MPU PL-6313 and an A / D converter integrated on the baseband processor MPU PL-6313, the A / D converter is connected with the output end of a two-dimensional acceleration sensor, and the output end of the baseband processor MPU PL-6313 directly outputs navigation data in a NMEA-0183 format. Thus, the method and the device realize the continuity of the positioning in urban and rural areas, solve the problem of difficult positioning and navigating in the GPS signal blind zones under high level bridges and in culvert tunnels and on sky ways, improve the GPS application range and performance to price ratio and have requirement on no other aspects such as vehicle improvement and installation position besides power supply.

Description

technical field [0001] The invention relates to a GPS device and a receiving method for non-blind zone navigation used for positioning and navigation of land vehicles. Background technique [0002] At present, the GPS (Global Positioning System, abbreviated as GPS) navigation device widely used in my country basically completely depends on GPS satellite signals. Under the influence of many factors such as the rapid development of urban three-dimensional traffic and the rapid development of high-rise buildings, many GPS signal blind spots have been formed. In this case, relying solely on GPS satellite signal receivers cannot perform normal and continuous positioning at all. Therefore, there is an urgent need for an auxiliary positioning device that can work in blind spots to ensure the continuity of navigation. [0003] At present, the methods that can realize assisted positioning mainly include: radio ranging assisted positioning, geomagnetic sensor assisted positioning and ...
